lI OO In use a llask 26 is placed upon the carrier 2 end the pattern(indicated at 27) is also arranged npon and attached to this carrier andin properrelation with respect to the flask. Guide-pins, as 28, are indcatedA for positioning the flask in respect to the pattern. The ilask isfilled with sand, which is properly rammed manually or in any desired orappropriate manner. The bottom board 29 is then applied to the flask andsuitably secured thereto. No means are shown for this purpose, becauseany ordinary and well-understood means, such as clamps, can be employedfor this purpose. Thereupon the carrier 2, and with it the patterns andflask and *its contents, is turned toward the left inFirg. 1 about thepart 3 as a center or fulcrum until the carrier rests upon the stop 11,and in this osition the carrier is at right angles to the direction ofmotion of' the frame 1, or, in other words, at rightangles to thestandards 4. The corner a ci the ilask comes to ya bearing upon theflask-receiving means or inth'e present instance, en erally speaking,upon the portion `b of the ed. The' result of this is that-the movableframe 1, which carries the o'epart of the carrier, rrises, while `thellas comes fto an' even bearing upon the flask-receiving means. It fwillbe seen ythat since thefulerum or hinge part ofthe carrier may riseflasks of Widelysdiiferent Vdepths may'betaceommodated between the =lasksupporting; nleanstand the .carrier Whewthe latter `isinthepositinvtldioatd by dotted lines in the left of F 1 Instead ofrelying uponlthecomer nf-the 'laskrin the `.mannendescribed usefma bemad-e -of the ladjustingecrew .23, 1Wbic l by contactingwith the'lu 24permits themovablezflzame to deseen .onlyvsulicientlyfarfoltacconnnodating the flasks, 4which for each adjustment of theset-sorew-should be of the same depth. To draw the patterns, the Vclampsare removed 'and the movable frame llis raised, for example, by meansol' the lever15,f;althoughit may be raised in any convenientway and bymeansof any appropriate mechanism. Since the vcarrier is held at rightangles tothe fralne, `as has been described, the result of raising theframe is to draw the patterns at right angles in respect to the plane ofthe flask, so that they may be successfully drawn even though they arerelatively deep. Cf course during the drawing operation use may be madeof a vibrator or rapping may be resorted to, or they maybe drawn withoutVthe1use of either of these. The finished Imold may then be removedpandythe described operations-repeated with other flasks. It may be remarkedthat the :accuracy of the alinement of 'the draft issuchin respect tothe sand that'the deep'pstterns `xnaynotvonly be successfully drawn butthey may `even be returned to the sand when it is necessary or'desirableto do so.

It is not m intention by the use onf-words or language 1n the foregolndescription to limit the invention further t an the state of the art mayrequire; but,

Having thus described the nature and 0bjeets of my invention, what Iclaim as new, and desire to secure by Letters Patent, is
